Abstract

Over the past decades, the majority of information and communication technology (ICT) products have undergone rapid technical change. To the extent that such technical progress benefits consumers and users, quality improvements should be reflected in official price and quantity indices. When this is not the case, there is a tendency to overestimate price movements and underestimate volume changes of ICT products. All statistical offices deal with this issue, but the degree and nature of quality adjustment of price indices of ICT products varies considerably across OECD countries. The present work does not venture to determine “best practice” for quality adjustment in statistical offices. However, it simulates measurement effects on key economic variables (real output, private final consumption, government expenditure, investment, exports and imports), and productivity, under the assumption that the price indices of ICT products are fully quality-adjusted. The paper draws on ... Les technologies de l'information et des communications : mesure de la production réelle, de la demande finale et de la productivité Au cours de ces dernières décennies, la majorité des produits des technologies de l'information et de la communication (TIC) ont fait l'objet d'une évolution technique rapide. Dans la mesure où ces progrès techniques profitent aux consommateurs et aux utilisateurs, les améliorations apportées à la qualité devraient être prises en compte dans les indices officiels de prix et de quantité. Quand ce n'est pas le cas, on a tendance à surestimer les mouvements de prix et à sous-estimer les variations des volumes des produits liés aux TIC. Tous les services de statistiques font face à ce problème, mais le degré et la nature de l'ajustement des indices de prix des produits des TIC en fonction de la qualité varient considérablement d'un pays à l'autre dans la zone de l'OCDE. La présente étude ne prétend pas mettre en évidence une "pratique exemplaire" d'ajustement en fonction de la qualité dans les services statistiques. Cependant, elle simule les effets des mesures sur des variables ...
